The Thompson/Center Muzzleloader Worm Patch Puller is manufactured from brass with stainless steel tines designed to remove those hard-to-get cleaning patches from your barrel. The patch puller attachment is fitted with 10-32 threads to fit almost any ramrod easily. Simply attach the patch puller to your ramrod and slide it down your barrel. With a little twist at the bottom, the worm tines will firmly grip the lost or stuck cleaning patch, promptly freeing your bore. The patch puller will make cleaning your traditional muzzleloader easier and help keep your .45 - .54 caliber Muzzleloader in tip-top shape.
